flltomey Patented Nov. 29, 1932 UNETED STATES PATENT OFFICE EARL E.CRONENWETH AND CHARLES G. HAMER, OF SAN FERNANDO, CALIFORNIA SPRINGOILER Application filed June 23,

This invention relates to an oiling device for springs of vehicles, andthe present invention is an improvement over that forming the subjectmatter of a patent granted to us on May 5, 1931, No. 1,803,748.

The principal object of this invention is to make each device in twoparts which are hingedly connected together so as to permit the parts tomove with the movement of the spring and to provide means for making thedevice more efficient than the device shown in the before-mentionedpatent.

This invention also consists in certain other features of constructionand in the com- .bination and arrangement of the several parts, to behereinafter fullv described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a side elevation of the spring suspension of an automobile showingthe device thereon.

Fig. 2 is a longitudinal sectional view through the device.

Fig. 3 is a section on the line 38 of Fig. 2.

Fig. 4 is a section on the line- 44 of Fig. 2.

In these views, the device is shown generally at A and one of thedevices is placed on each half of the spring B, and each devicecomprises an inverted channel-shaped part 1 and a lower channehshapedpart 2 which telescopes into the part 1, the side edges of the part 1flaring outwardly as shown at 3 so as to permit free movement of theparts.

Each of the parts 1 and 2 is formed of two sections which are hingedlyconnected to gether as shown at 4, the adjacent ends of the two sectionsbeing beveled as shown at 5 so as to permit free movement of the devicewith the spring.

The small end of the device is held on the small end of the spring bythe clip 6 and the outer end of the bottom part of the section member 2is curved downwardly as shown at 7 to fit over the bolt 8 of the clip asshown 1931. Serial No. 546,390.

in Fig. 2 to prevent movement of the device towards the axle C of thevehicle. This hookshaped part 7 can be formed separate from the bottomand suitably fastened thereto such as by rivets or the like.

A metal strip 9 is riveted to the bottom of the member 2 at the smallend of the device and its ends turned over upon the pad 10 as shown at11 in Figs. 2 and 4, so as to firmly hold the pad in the bottom of thedevice.

The two members 1 and 2 are resiliently held on the spring by the upperand lower cross bars 12 which project beyond the sides of the device andhave notches 13 in their ends for receiving the hooks formed at the endsof the springs 14 as shown in Fig. 3. One of these spring assemblies isplaced at the large end of the device and another spring assembly isplaced at the hinged end of the smaller section as shown in Fig. 1.

I It will of course be understood that the device is formed with the oilreservoir 15 and the wicks 16 for leading the oil therein to the pad 10as in the patented device and the device is also provided with thegaskets 17 at its ends as in the patented device.

From the foregoing, it will be seen that we have improved the patenteddevice by providing means for holding the front end of the pad inposition so that the pad is firmly held in the device, with improvedmeans for yieldingly causing the two parts of the device to engage thespring so as to keep the oil saturated pad against the bottom of thespring, and by making the device in two sections hingedly connectedtogether, the device has more movement than the patented device, and cantherefore adjust itself to the movements of the spring.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

Having thus described our invention, what we claim as new is 1. A deviceof the class described comprising a casing formed of upper and lowerchannel-shaped members telescopically arranged, a pad in the lowermember, a clip attached to the bottom of the lower member and engaging apart of the pad, spring means for pressing the two members towards eachother, the bottom of the lower member having a hook-shaped part at oneend, and a clip encircling the device and having a part thereof engagedby the hook for preventing longitudinal movement of the device.

2. A device of the class described comprising a casing formed of upperand lower chan- 5 nel-shaped members telescopically arranged, eachmember being formed of two sections hingedly connected together, a padin the lower member, upper and lower cross bars engaging the top andbottom of the device,

' springs having their ends connected to the ends of the cross bars,said device tapering from one end to its other to conform to the shapeof a spring, a clip encircling the small end of the device and thebottom of the lower member having a hook-shaped part for engaging a partof the clip.

3. A spring oiler of the class described comprising upper and lowerchannel-shaped members, the upper member being inverted and having itslimbs fitting over the limbs of the lower member, each member beingformed of channel shaped sections the bight portions of which arehingedly connected together, and the inner ends of the flanges of thechannel-shaped sections being beveled with said beveled ends convergingtowards the hinge, a pad in one of the channel shaped members, andspring means for moving the members towards each other.

In testimony whereof we afix our signatures.

EARL E. CRONENWETH. CHARLES G. HAMER.
